Openstack / Reboot Server Soft Or Hard
Reboot Server Soft Or Hard
Reboots a specified server instance with either soft or hard options.
openstack server reboot --soft --wait <instance_id> openstack server reboot --soft --wait <instance_id> #!/bin/bash
# Reboot Server Soft Or Hard
openstack server reboot {{--soft|--hard}} --wait {{instance_id}} import subprocess
# Reboot Server Soft Or Hard
# Make sure to replace <placeholders> with actual values
def run_command():
cmd = [
"openstack",
"server",
"reboot",
"--soft",
"--wait",
"<instance_id>"
]
try:
print(f"Executing: {' '.join(cmd)}")
subprocess.run(cmd, check=True)
except subprocess.CalledProcessError as e:
print(f"Error: {e}")
except FileNotFoundError:
print("Error: openstack not found. Please install it first.")

run_command() When To Use
After deployment changes requiring a refresh of the instance environment.
Pro Tip
Using `--soft` performs a graceful reboot; `--hard` risks data corruption if unsaved changes exist.
